O-Ring 27x3 MVQ 70 ShA Silicone Seal

Silicone O-Ring for Industrial Sealing Applications

High Temperature and Aging Resistance

Hydraulic, Pneumatic and Technical Sealing Use

Main Description:
The O-Ring 27x3 MVQ 70 ShA is a precision-manufactured silicone rubber gasket designed for professional industrial sealing applications. Produced from MVQ silicone elastomer with a hardness of 70 ShA, it provides reliable static sealing performance across a wide temperature range.

With an inner diameter of 27 mm and a cross-section of 3 mm, this O-Ring is suitable for sealing covers, housings, flanges, connectors and various mechanical assemblies. As a static seal, it ensures tightness in systems exposed to thermal fluctuations, environmental factors and long-term operational stress.

MVQ silicone material is known for its excellent resistance to high and low temperatures, UV radiation and aging. The O-Ring maintains flexibility at low temperatures and dimensional stability at elevated temperatures, typically operating from around -50°C up to +200°C depending on working conditions. This makes it a preferred technical sealing component in HVAC systems, food processing equipment, medical devices and industrial machinery.

Compared to standard rubber seals, silicone O-Rings provide improved performance in extreme temperature environments and applications where ozone and weather resistance are required. The 70 ShA hardness offers an optimal balance between elasticity and mechanical strength, ensuring uniform compression within the groove and minimizing leakage risk.

Supplied in a pack of 100 pieces, this industrial sealing solution is ideal for maintenance departments, service companies and technical wholesalers requiring consistent availability of high-quality sealing components.

The O-Ring 27x3 MVQ 70 ShA is a dependable rubber gasket for hydraulic and pneumatic applications where temperature stability and long service life are essential.
